MINE-CAR COUPLER.

Application filed me 1?, 922. Serial No. 569,174.

To all whom it may concern 7 Be it known that we, Pn'rnron J. ELLIOTT and EDWARD L. BONAMY, subje t of Great Britain and a citizen of France, respectively,

residing at Newcastle, county of King, and

State of lvashington, have invented a. new.

and useful Minellar Coupler; andwe do hereby declare that the following is a full. clear, and exact specificatlon, such as wlll enable others skilled in the art to which-it up vide a device with lugs on its interior surface which will slip into slots in the tongue of a car and remain in place while the car is being pulled but which will slip outo'j place and release the car the cablethat is pulling itis raised .to a vertical position.

Another object of the invention is coprovide aframe with a roller at the end above a track so that as a cable pulling a carpasses over the roller when the ear is releasedit will drop elf the [side of the frame auto-- matically to a position-in front of another car so that it may be readily attached to the car. 1

lVith these ends in view the invention embodies an inverted U shaped bracket with slantinglugs on the inside of its vertical sides and trunnions on the outside. The trunnions have straps pivoted on them whose opposite ends are bent inward and pivoted on a pin on which is also a bar uhich has a link in its outer end to which the end of a cable is attached and whose inner end projects backward under-the bracket.

Qther features and advantages of the in-- vention will appear in the following de-. scription taken in connection with the drawings, wherein,

Figure l is a side elevation.

Figure 2 is a bottom view. 7

Figure 3 is a general view showing the frame which causes the coupler to release and drop down to the next set of cars.

In the drawings we have shown'our device as it would be constructed wherein, numeral 1 indicates the inverted U shaped bracket which has lug-s 2 on the inner side of its vertical members and trunnions 3 on the outside of them. The lugs 2 fit in slots 4. of a car tongue 5 and both the lugs and slots are made in a slanting position as shown. by the dotted lines in Fi The straps G are Lpirotally mounted rui'lnions 3 and their opposite 'en'ds which are bent inwaid as. shown in Figure 2 and pii'ocally mounted on the bolt 7 in which is also the bar 8. in the outefend 'o'l'" which'is a link 5) by which the coupler isattachcd to'tbe end of a cable. At the innerend otthe' bar 8 is a point ltl whichis formed. by cutting gray the upper part of the bar shown in I In l igure pulling full the car arrlv car 12 out of a mine and as cs at the dotted position indi 3 we have shown a cable 11 cated by the numeral 18 the cable It which runs over a roller 1%: will be in practically a rertical position so that the outer end of the coupler will rise to the dottedposit'ion shown in l igure 1 in :which position the'lugs 2 will slide upward out of the slots 4-.fand thereby release the cable frointhe end ofthecar.

The end of the cable will then drop on top of the frame '15 and the illCllHQd bar 16 Wlll cause the cable to slide off the end of the frame. A row of'einpty cars 17 standing on a sidii'ig besidethe' frame may then be fastoned to the end ofthe cable and run down into the mine. From the illustration it may be observed that there may be two cables and the frame may-have two sides with a partition 18 in the middle and another sid-' .ing for empty cars may be placed onthe other side of the frame. In which case the cable 11 will handle the cars on the far side of-the frame and the cable 19 will handle the cars on the near side of the frame.

It, will be understood that changes may be made in the construction without departing from the spirit of the invention. One of which changes maybe in the use of two or more lugs on the sides of the bracket 1 in- .stead'of one as shown. Another may be in the changing ofthe slope of the lugs. And still another may be in the design of the bar 8 or in the method of attaching it to the. cable. 7

The construction will readily be understood from the foregoing description. use the device a slanting slot should be placed in each side of a car tongue. and the Ushaped bracket placedover it with the lugs going into the slot. seen that as the coupler is pulled forward the beveled edges of the lugs will cause the bracket to pull downward against the top ice It will be 1 of the ton ue 50 that it will be im )ossible for it tosiip off until the outer end cit, the coupler has been raised as hereinbe't'ore described. It Will be seen that inorder to uncouple the car it Will only be necessary to push upward on the under side of the bracket. I

Having thus fully described the invention what We claim as new and desire to secure by Letters Patent is 1. A device of the type described embodying an inverted U shapedbrecket having slo oin lu s on the inner sides of its veron the inner sides of the vertical members of the bracket; pins projecting from the outer side of the vertical members of the bracket; links oivotally mounted on the pins Whose opposite ends are bent together and pivotally mounted on another pin; bar pivotally mounted on this pin betWeen the links; a hole in the outer end of the bar for attaching it to the end of a cable; a projection on the inner end of the bar and the cutting of slots in the sides of a car tongue.
